Note: - BOOST_PP_IF does not get disabled
IF getting disabled doesn't matter here. The entire ENUM_PARAMS invocation occurs on entry to IF--where IF is not get disabled.
Right, otherwise "BOOST_PP_CAT(f,BOOST_PP_CAT(o,o))" wouldn't work...
#define BOOST_PP_LOCAL_MACRO(i) I must not post rubbish when in a hurry. // ... ;-)
Thanks for correcting,
Not rubbish. Your solution was the correct one--move the invocation of ENUM_PARAMS out of the input to IF.
Oh - I don't think my whole post was rubbish, but that note sure was (and due to quick-posting). I'll cite myself on the very same topic some weeks ago: Rescanning happens /after/ argument substitution [ 16.3.4.-1 ] and the replacement restrictions for rescanning [ 16.3.4-2 ] do not apply for argument substitution [ 16.3.1 "A parameter in the replacement list [...] is replaced by the corresponding argument after /all/ macros contained therein have been expanded" ]. Hmmm...

I hope to understand more after reading your reply to my Chaos questions (no need to hurry). BTW. should I better ask somewhere publicly (the seemingly dormant Sourceforge forum of the chaos-pp project, perhabs) rather than in private email? Regards, Tobias
